To all whom it mag concern: I

Be it known that I, EDWARD W. OUsLnY,

' a citizen of the United States,residing at St. James, in the county ofPhelps and State ot Missouri, have inventedcertain'new and usefulImprovements inGold-Dust Col lectors; and I do declare'tlie following tobe a full, clear, and exact description of the invention, such as willenable others'skilled in the art to which it appertains to make and usethe same. i p

This invention relates todustcatchersand moreparticularly to that classof dust catcherswlnch are used in dentalwor'k orfwhenever abradingoperations are c'arried'on upfon valuable material, the d'ust'of whichitis desired to collect and save. The principal object of my inventionis to provide an improved dust collector of this character which maybereadily attached'to theperson of an operator or secured to a stationarysupport as desiredand is provided with a receptacle at its lower end forI o e g the dust therein which may b readily detached from the main bodyof the collectorwhen'ever desiredp Another object of my invention is toprovidea device of this character having a 'fora'minous' guard whereby,should the plate or material being Worked upon be .acciclen tallydropped Withinthe body of the collector, it wiljl be prevented frombecoming lodged in the du t collecting receptacle car ried on the lowerend of'the collector.

With these and othergenieral objects in view, which will appear from thedescription, my inventioniresides in the novel combination, constructionand arrangement of parts to be hereinafter more fully described andclaimed and taken in connection with the accompanying drawing whichforms part of this application and in which:

Figure 1 is a front elevation illustrating the manner of application ofmy invention; Fi 2 i a Side. elevation of the same;

Fig. 3 is a vertical central sectional view of'mycollector; i

Fig. 4 is'a rear elevation thereof; v

,Fig. 15 is a perspective view ofa suppor for the collector;

, Fig. 6' isa side elevation showing my collector as attached tothe'wall or stationary v suppo rt.

Briefly described, mylinvention comprises substantially a funnelsshapedbody provided With a detachably secured dust collecting re:

ce'p'tacle. on its, lower end and having efz'itended across its top anarched transparent guard member. The sides of the body below the archedguard member are deeply recessed in order to provide apertures there-'.

through". for the insertion of the hands of an operator and thebodyportionof the collector is provided with a hingedly secured:hoolnwherebyit may be suspended from the shoulders of an operator. Anadditional attachingmeinber isprovided at the back of thereceptaclewhereby the, same may be secured upon a Waller any suitablestationarysup'port as desired. Means are also provided at the lower endof the body to prevent the dropping into the dust collecting receptacleof any plates or other materials being worked upon, should the samebecome accidentally disengaged while being held within the bodyv of thecollector. l

Referring more particularly to'the drawings and describing my inventionin detail,

my improved collector comprisesa substanv tially funnel-shaped body 1having a fiat rear side 2 anda substantially similar front" side Thebottom of the body 1 terminates in a spout 4 provided with anannular-shoulder 5 depending rtherefrom' and internally threaded'toreceive therein the externally threaded head of adust collectingreceptacle 6 which may be composed of any suitable] material which inthis embodiment comprises glass, Adapted; tobe disposed inthe shoulderportion :5 and resting on the head foraminous guard member 8 whichextends across the mouth of the dust collecting yreceptacle and. formsan effectual guard, whereby to permit the passage therethrough of thesmall particles of dust to be collected, and which will prevent thedropping oflarge pieces of material therethrough, should they becomedisengaged from the toolsused by the operator.

The front Wall or side or the body or my.

of the receptaclefi is a' frame 7 carrying v improved collector isprovided with an'u p' wardly extending lip .9 and therear wall 2' a p vis provided with a similar upWardlyeXte-nding portion 10 having itsupper edge dispose-dconsiderably above the upper edge of the projectinglip 9 on the front wall 3 of. the collectonf The upper edges ofthe lip'9 and upwardly extending portion 10 are tormedflof equal length and areconnected at their side edges by 'meansof a pair of arched metal strips11 suitably secured at o their ends to the upper edges of thep'orti' o'nand lip 9a nd between which is extended and securedthereinga sheetoftransparent.

may be enabled to examine thework held Owing; to the disposition of theupper edges ofthe upwardly extending portion 10 of the rear wall 2 andthe lip?) o11 ,tl1e .front I wall 3,:the 'arched'strips or name support'ing 'membersfll will be extended down wardly at thefrontwall of:thecollector and} having-a transparent guardmember secured therebetweenwill .providenot only a transparent topfforthereceptacle but atransparc-eptacleas well, thereby insuring a; more efliclient lightingof the interior of the collector. Spaced below the arched supportingstrips 11, the side edges 121015 the body of the reprojecting portion"and the lip aredeeply recessed to provide suificlently large aperturesat'the sides of the collector, whereby to permit, the insertionof anoperators hands to manipulate tools within the interior of thecollector. Between the edges of the aperture thus formed andthefront andrear walls 01' the body of the collector islefta suitable margin so thatthe hands of an operator when engaged in theapertures will efi'ectuallycloseithe same.

{As a means of providingasupport for the collector, I provide a rod'l3hingedly con nected to the back of the'collector bymeans of a flange 1dformed on the upper edge of the v projecting portion 10 andsurroundingthe rod. 13 to retain the same thereon. At its wardly extending portions15 having hooks 16 formed on their upper ends and adapted r 'to beengaged over theshoulders oflan operopposite ends the rod is providedwith up ator when-it is desired to use the collector.

' :Owing'to the flatrear side of the body'lofthe collector, when thesame isengaged with the hooks over the shoulders of an"oper ator,turningor twisting of the body 'of the collector will 'b'e effectuallyprevented. An

aperturedfflange 17 is formed on the upsupported on the wall or on astationary cent the lower" portion of the body of the collector upon asuitable support.

:l beunderstood that I donot limit myself I specifically to thesedetails as shown and described as it is obvious that the body of thecollector may be made of any suitable materialjinstead of aluminum whichI preferably employ and that minor changes in :thedetailsof itsconstruction may be made without in any way departing from the spirit ofmy invention and defined between the scope of thevfollowingclaimsIclaim: 7 1.
